Bombardier Cells gate your Refiner Level 3 upgrade. No cells, no upgrade — simple as that.

The catch: Bombardiers are loud, explosive, and every squad on the map hears the fight. Killing one is easy. Keeping the loot is the hard part.

Here's the fastest, safest way to farm them.

What Bombardier Cells Are For

Dropped by Bombardiers — rocket-firing ARC mechs. Main use: Refiner Level 2 → 3.

Bombardiers usually roll with flying spotters. Kill those first — they track you and turn a clean fight into a mess.

Best Farm Locations

Plaza Rosa (Buried City) is your first stop, full stop.

If Plaza Rosa is empty, rotate to Marano Park. No point standing around burning raid time.

Reported respawn window: ~6 minutes. Worth camping if the lobby's quiet.

How to Spot a Bombardier

• Large ARC ground unit with rocket/mortar fire
• Flying spotters nearby = confirm it's a Bombardier
• Explosive impacts = loud, other Raiders will hear it too

See spotters before you see the Bombardier? Slow down. That area's already active.

Best Loadout to Kill Them Fast

Don't bring a weak loadout. Slow kills = free real estate for third parties.

Recommended kit: ARC-focused primary + Trailblazers + smoke grenade + extra healing. Bring more ammo than feels necessary.

Why Trailblazers Win

• Shorter fight = less rocket exposure
• Less noise time = fewer squads showing up
• Faster kill = faster loot window before it becomes a battlefield

Getting Trailblazers

Blueprint hunting spot: Stella Montis — Western Tunnel toward Lobby Metro, Assembly Workshops upstairs rooms, small containers. Assembly Workshops is contested — grab and go, don't linger.

The Farming Route

1. Queue Buried City

2. Push to Plaza Rosa

3. Scout before engaging — don't walk into another squad

4. Kill spotters first

5. Fight from hard cover (walls, interiors, not open ground)

6. Burst the Bombardier with Trailblazers

7. Smoke the husk before looting

8. Extract or wait ~6 min for respawn

Because Bombardiers fire explosives, hard cover beats distance every time. Thin cover won't save you from splash.

Combat Rules That Matter

Target the torso and legs — better hit results than random spray. A missed Trailblazer isn't just wasted damage, it's wasted materials and wasted time you don't have.

Solo Strategy

Solo farming works, but patience is the whole game.

1. Approach Plaza Rosa, don't rush the open square

2. Let other squads fight and leave

3. Kill spotters

4. Burst damage, smoke, loot

5. Extract immediately after

Late-raid method: hide near Plaza Rosa early, let other teams clear each other out, engage when traffic drops. Slower, but way safer if you only need 1-2 cells.

Squad Strategy

Assign roles before you engage — chaos gets people killed.

If a squad approaches mid-fight: finish fast and disengage, or back off entirely. Don't panic-loot.

Drop Rates & Timing

• ~2+ cells per successful kill in most reports
• Respawn: ~6 minutes, same location
• If you've already got what you need — leave. Farming one more is how runs end badly.

Mistakes That Cost You the Loot

Bombardier Cells are progression loot, not normal loot. Once they're in your bag, the mission changes to survive, not farm more.

FAQ

Where do you get Bombardier Cells?

From defeated Bombardier ARC units. Plaza Rosa, Buried City is the most consistent spawn.

What are Bombardier Cells used for?

Upgrading the Refiner to Level 3 — a key progression bottleneck.

What's the best weapon against Bombardiers?

Trailblazers for fast burst kills. Hullcracker and Anvil are solid alternatives.

Can Bombardiers respawn in the same raid?

Yes — around 6 minutes, especially in reliable zones like Plaza Rosa.

Is farming Bombardier Cells solo viable?

Yes. Use cover, clear spotters first, smoke before looting, and extract right after getting cells. Late-raid timing is safer for solos.

Bottom Line

Buried City, Plaza Rosa, Trailblazers, smoke, extract. That's the loop. Kill spotters first, fight from cover, burst the Bombardier fast, and don't get greedy once the cells are in your bag. One clean extraction beats two greedy fights every time.
